SAL 40 Years Anniversary Seminar on 9 January 2025

Date of Publication: 23.12.2024

The Systems Analysis Laboratory was founded in 1984. Since then, more than 640 MSc students have graduated from SAL, and the number of doctoral graduates has reached 85. This seminar appraises the significance of systems and operations research from the perspectives of education, research, and societal impacts. It also explores what competencies and research advances are needed to navigate in the face of uncertainties. For the detailed programme and registration form (DL 6 January), see https://www.aalto.fi/en/events/systems-analysis-laboratory-40-years 


A Public Lecture by Prof. Giovanni Pantuso

Date of Publication: 28.08.2024
In this talk, I present an exact solution method for two-stage stochastic programs under decision-dependent uncertainty. In such problems, first-stage decisions determine the probability distribution of second-stage uncertain parameters.  Particularly, we focus on a broad class of problems where the number of potential probability distributions is finite but exponentially large. In these problems, the recourse function is non-convex and discontinuous even for problems with continuous second-stage. The proposed method extends the well-known L-Shaped method and is applicable also to two-stage stochastic programs with integer variables at both stages. We show that the algorithm converges finitely and propose a number additional improvements that facilitate convergence, such as valid inequalities. Results of numerical experiments on a facility location problems under endogenous uncertainty show promising scalability and efficiency also on very challenging problems.
